Convert JPG to AVIF Online

AVIF (AV1 Image File Format) is the newest and most efficient raster image format for web use, derived from the AV1 video codec developed by the Alliance for Open Media. AVIF achieves 20–50% smaller file sizes compared to JPEG at equivalent visual quality, outperforming even WebP for most photographic content.

AVIF also offers HDR (High Dynamic Range) support, 12-bit colour depth, and both lossy and lossless modes - Capabilities that JPEG simply cannot match. For web developers targeting modern browsers, AVIF represents the state of the art in efficient image delivery. Browser support reached 90%+ in 2024, covering Chrome 85+, Firefox 93+, Edge 121+, and Safari 16+.

The trade-off is encoding time. AVIF encoding is computationally intensive -typically 5–30× slower than JPEG encoding. For online conversion of individual images this is barely noticeable, but for batch processing thousands of images on a server, encoding time becomes significant. AVIF is also not universally supported yet in all email clients and older browsers, where JPG fallbacks remain important.

AVIF (AV1 Image File Format) was finalised in February 2019 by the Alliance for Open Media — a consortium including Google, Netflix, Amazon and Mozilla. It wraps a still frame of AV1 video in an ISO base media container, inheriting AV1's royalty-free licensing and aggressive compression. AVIF typically delivers 50 percent smaller files than JPEG at equal visual quality and outperforms WebP and HEIC at low bitrates. Chrome shipped support in 2020, Firefox in 2021 and Safari in 2022, making AVIF the first truly modern web image format with broad browser backing.

AVIF (AV1 Image File Format) is the most efficient compressed image format available today, typically 30–50% smaller than JPG at equivalent perceptual quality. Converting your existing JPG images to AVIF is one of the highest-impact optimisations you can make to a web project - It reduces bandwidth consumption, cuts CDN costs, and dramatically improves page load times, particularly on mobile connections.

AVIF is supported in Chrome 85+, Firefox 93+, Edge 121+, and Safari 16.4+, meaning it covers the majority of current browser usage. For web developers, serving AVIF via a <picture> element with a JPG fallback gives you maximum performance for supported users without breaking compatibility for legacy browsers.

Streaming platforms, social media companies, and large e-commerce sites have adopted AVIF for their image delivery pipelines because the bandwidth savings at scale are enormous. A site serving 10 million images per day can save tens of terabytes of monthly transfer just by switching from JPG to AVIF.
